To appease the little screen addicts I've been pondering what to do about this 'videos not available' thing on You Tube- as it's going to keep on happening until such time as the music companies and YT sort themselves out- so from now on whenever there's a new video, I'm going to post it both to the usual YT channel and also onto Vimeo, which seems to have no such restrictions on music use. Here's the current Progress video, which seems to look much nicer on Vimeo than on YT, and which is also working nicely on my phone.
